Question for the scientifically-minded:
As an endurance athlete and former #EMT But I have been thinking about this for maybe the past week or so.
Elite marathon runners train at high altitudes where the air is thinner and then run races at lower elevations where the air is denser. But...
What would happen if someone did brutal cardio workouts (assault bike, rowing machine, ski, etc.) in a hyperbaric chamber? How would performance, anaerobic fatigue, endurance be impacted? Nothing more than 2 ATA (66 feet-salt water) to start.
Understanding the blood and muscle tissue would be highly saturated with O2, far more than what hemoglobin would normally carry, does this mean the athlete would feel "supercharged"? On the other hand, what dangerous would arise? There are questions surrounding gas exchange. Would the body be able to clear the CO2? Initially, more oxygen = more performance but the body responds to stress and hypoxia.
It's an interesting idea. Thoughts, anyone?

Brewing oceans, brewing storms, making a blooming disaster
"Over the past year, Australia’s oceans have been hotter than ever before...The continued burning of fossil fuels has caused our atmosphere to warm by approximately 1.2 degrees C since the pre-industrial era....If you change what happens in the oceans, you start to change the whole system...The problem with climate change is we’re hitting that system incredibly hard with extra energy and we’re putting a lot of pressure on the oceans."

Global oxygen decline in the ocean
Ocean hypoxia: The science of climate change in the sea
"... The field will need to draw on ... advances to meet demands for adaptation solutions to the continued progression of global ocean deoxygenation, particularly in conjunction with ocean acidification and marine heatwaves in a multi-stressor scenario."

Laughing gas, also known as nitrous oxide, is a widely used medicinal gas that can be deadly when used recreationally. In this video, Dr. Howard Smith explains the risks of nitrous oxide use and how it can lead to serious health problems. From oxygen deprivation to neurological damage, the consequences of laughing gas misuse are severe. Don't let this happen to you or your children - educate yourself and others on the safe use of nitrous oxide.
Delivery day for the oxygen cylinders!
I got help loading them in the truck when I picked them up at the delivery point in Alamogordo.
Back home, I'm alone and the unloading was slower and deliberate. Fortunately, I only had to lower the cylinders off the bed. Raising them would have required a ramp or other equipment.
I got them into the garage before the next monsoon rainstorm.
I need to make a wall rack to hold them upright, safely, securely. I think I need to get a 20-foot stick of 1-inch square steel tubing from the world famous Basin Pipe and Metal.
Can I make an air liquefaction plant?
